BACKGROUND OF THE INVENTION

I. Field of the Invention

This invention is generally directed to the field of agriculturemachinery, and more particularly, it relates to a preplanting tillageimplement used in combination with a seed planting device. Specifically,the invention relates to a rolling basket tillage implement used intandem with a seed planting implement in which the rolling basket mayhave an independent height adjustment aspect.

II. Related Art

In the spring, prior to planting, farmers must prepare their fields foraccepting seed. Many tillage implements have been designed and are usedto condition the soil in preparation for planting. Traditional farmingincludes both primary and secondary tillage tasks to prepare the soilsuch as plowing, disking, field cultivating and harrowing. Disking is anexample of a method of primary tillage and harrowing is an example of amethod of secondary tillage.

Primary tillage is a first pass over the soil using a soil conditioningimplement attached to the rear of a tractor which works deep into thesoil. The soil is usually worked about four inches deep to break upclods of soil, remove air pockets, and destroy weeds deep in the earth.Secondary tillage involves another pass over the same soil, at a moreshallow depth, using implements which are generally attached to the rearof the primary tillage unit such that the secondary tillage unit followsthe primary tillage unit. The secondary tillage unit generally works thesoil to a depth of about two inches.

The secondary tillage unit is usually a final conditioning tool toprepare the soil for planting. Such units may chop up crop residues,break up soil clods and break up any crust on the top of the soil,provide weed control, incorporate chemicals into the soil, and stir andfirm the soil closer to the surface.

Rolling basket seedbed finishers represent an important type ofsecondary soil conditioning implement. Rolling baskets are primarilyused as soil leveling devices to break up and minimize clods of soil andto remove air pockets from the soil. Farmers obtain great benefit fromusing rolling baskets as a means of secondary tillage to provide a levelsoil for planting. The ability to break up clods of soil, remove airpockets and further incorporate chemicals generally leads to better cropyields at harvest.

Accordingly, it would be beneficial if a secondary tillage operationusing a rolling basket could advantageously be combined with a plantingoperation such that one could take immediate advantage of soil incondition for planting by accomplishing the planting project during thesame pass over a field. Thus, the attachment of rolling basket tillagefor use in conjunction with a seed planting implement would bedesirable.

However, the use and effectiveness of rolling baskets or other soilconditioning implements is greatly limited by the condition of the soil.If the soil is too wet, rolling basket soil conditioning implements maybecome filled and clogged with soil which make them useless for furthersoil conditioning until they are again emptied of soil. When a farmerrealizes that areas of soil in a field are too wet to use suchimplements, he will generally forego the use of such soil conditioningimplements entirely for the season. This means that much of the soil maynot be properly treated and an expensive farming implement will layidle. This is not a desirable or economically efficient situation forfarmers.

It would, therefore, also be beneficial to provide an arrangement ormechanism that enables intermittent use of a soil conditioningimplement, particularly a rolling basket seedbed finisher, and/or aplanter in a field where areas of soil are dry enough for use, but wherethere are also areas which are too wet for use. Such a device wouldallow a farmer to raise rolling basket seedbed finishers above the soiland out of use whenever they reach a section of a field where the soilis too wet and thereafter enable the rolling basket finisher to belowered and reconnect with the soil in areas where the soil is suitablefor use.

SUMMARY OF THE INVENTION

The present concept is related to combining said conditioning implementin the form of rolling basket seedbed finishers with planters toaccomplish multiple tasks in a single pass. An aspect of the presentconcept relates to mounting rolling basket seed finishers on plantingequipment. A further aspect of the present concept is related to amounting assembly for a soil conditioning implement in the form of arolling basket seedbed finisher. The mounting assembly is for individualrolling baskets which are a part of a plurality of such soilconditioning implements generally arranged in a spaced aligned manner ona multi-row planter, seed drill or other implement, which is used todistribute seeds into the soil, hitched to and pulled by a tractor orother prime mover.

Certain embodiments of the mounting assembly include a height adjustablemounting arrangement for each of the rolling basket soil conditioningimplements. Each height adjusting mechanism includes an actuator foradjusting the relative height of a corresponding rolling basketindividually, and an associated control system for operating the heightadjusting mechanism. The actuator preferably includes a hydraulic orpneumatic cylinder, which may be single or double acting. It is also anaspect of the present invention for the mounting assemblies andassociated implements to be combined with a planter and arranged suchthat rolling basket soil conditioning takes place in front of eachindividual seed planting unit on a planter.

In a preferred embodiment, each mounting assembly for each rollingbasket soil conditioning implement may be controlled from a centralcontrol system that includes control switches or a control pad, or thelike, having a control device associated with each rolling basketlocated in the cab of an associated tractor. In this manner, a user isable to adjust the height of each mounting assembly individually andtherefore the height of each associated soil conditioning rolling basketimplement may be adjusted individually as needed.

It will be appreciated by those skilled in the art that a plurality ofactuator devices such as pneumatic or hydraulic cylinders, or the like,together with the necessary controls can be connected to be operatedfrom the cab of a tractor or other farm implement device prime mover byconventional means in a well known manner.

In other embodiments, the rolling basket devices may be fixed to theplanter and other mechanical devices may be used to apply varyingdegrees of force to the soil being processed. These include compressionor torsion springs, inflatable air bags, shock absorber devices whichmay be spring loaded, or the like. Air bag systems may be single ordouble acting.

An aspect of the invention is directed to an adjustable mounting bracketassembly for attaching a soil conditioning implement in the form of arolling basket device, particularly to the frame of a planter.

As shown in the embodiment of FIGS. 3-8, the mounting assembly 2, for arolling basket soil conditioner 10 comprises at least three parts, aheight adjustable mounting 4, a height adjusting mechanism or actuator,which may be in the form of a hydraulic (6A in FIG. 9E) or pneumaticcylinder 6, and an associated control system (FIG. 10) for operating aplurality of such height adjusting mechanisms to adjust the height of aplurality of spaced associated connected rolling baskets as normallyused in tandem with a planter as towed by a tractor.

As illustrated in FIG. 3, the height adjustable mounting 4 is composedof several parts including an attachment plate 12 and a pair of spacedparallel side plate members 16 and attachment arms 18 for coupling therolling basket soil conditioning implement to the attachment plate 12.The attachment plate 12 is adapted to be fixed to the frame of a farmingimplement in the form of a conventional planter along with theattachment plates of other units such that the soil ahead of eachplanting unit is conditioned.

Each mounting assembly includes spaced arms 18 which extend away from anassociated rolling basket soil conditioning and leveling implement 10which is journaled for rotation between the arms 18 as at 20. The arms18 connect to the members 16 fixed to the attachment plate 12. The arms18 are connected to each other by a common crossbar 24 which alsosupports one end of a cylinder or actuator 6.

As illustrated in FIGS. 3 and 4, the arms 18 and the members 16 of theattachment plate 12 are designed such that they pivotally connect toeach other. Any manner known in the art which connects and enables thearms 18 to pivot at 22 relative to the members 16, such as bearings,bushings, etc., can be employed so that the adjustable mounting 4 isable to move towards and away from the surface of the ground with theoperation of cylinder 6 which may be attached using a clevis arrangementas at 26 to attach the rod end and a bracket arrangement as at 28 toattach the blind end of the cylinder 6 to the attachment plate 12.

The height adjusting actuator 6 may be a hydraulic or pneumaticcylinder, or other devices, as illustrated, those skilled in the artwill recognize that any mechanical mechanism able to raise and lower thesoil conditioning implement 10, as shown in FIGS. 5 and 6, may be used.Thus, in some embodiments, height adjusting depends on raising theplanter with the rolling baskets attached. In those embodiments,downward force may be provided by a spring-operated mechanism, aninflatable air spring, or any similar system known in the art, such asare shown in FIGS. 9A-9D. As indicated, several preferred embodimentsutilize pneumatic cylinders as compressed air is generally available ontractors to connect to and operate farm implements. It will berecognized, however, that hydraulic systems are also commonly used inthese types of applications.

The rolling basket units 10 further include a pair of side plates 30connected by a plurality of spaced steel bars 32 which may be internallyor externally attached to the plates 30. A central spindle or axle 34 isalso provided.

FIGS. 5, 6A, 6B, 7A and 7B also depict a planting implement 35 having aseed distributing arrangement 36 (FIG. 6B) and a connecting frame 37including a main structural member 38 that connects together a pluralityof similar units 35.

As shown in FIGS. 5 and 6A, the operation of the actuator 6 serves toraise and lower the soil conditioning rolling basket implement 10 inaccordance with the operation of a control system. It should be notedthat in an implement carrying a plurality of soil conditioning rollingbaskets 10, as shown in FIG. 10, an associated control system enablesthe raising and lowering of the soil conditioning implementsindividually as desired by the operator in the tractor or other towingvehicle. It may also enable the soil conditioning implement 10 to bepositioned in a floating mode riding the soil surface or lowered withapplied force as needed.

An alternate embodiment of the mounting bracket assembly is showngenerally at 102 in FIGS. 1 and 2 and also includes a height adjustablemounting 104. That system utilizes a shell or shroud 114 covering theupper portion of the rolling basket 110. Pivotally connected members 116and arms 118 are shown together with mounting bracket 120 and clevisattachment 122. The actuating cylinder or other such device is notshown.

FIG. 10 is a schematic drawing of a soil conditioning system used with amulti-row seed planter so that a field may be properly leveled andthereafter receive seeds from the planter modules. In this schematicdrawing, a tow bar 40 is connected to a trailer tongue 42 that isadapted to be connected by a clevis (not shown) to a towing workvehicle, such as a farm tractor. Secured to the tow bar are a pluralityof rolling basket tillage devices 44.

Primary tillage devices (not shown) may, for example, comprise diskharrows or rake harrows of conventional design known in the art may beused prior to employing the rolling baskets. As previously explained,the primary harrows are arranged to dig deeper into the soil andtypically produce clumps depending on soil type and moisture content. Itis preferable that the clumps become crushed and broken up and the soilleveled by the action of the secondary rolling basket devices 44 leavingthe field prepared to receive seed at the time of seeding and the seeddistributed by planter modules 46.

The user or driver of the tractor or other prime mover determineswhether the soil is too wet for the soil conditioning implements 2 toeffectively work or not. If the soil is too wet, the user sends a signalvia the control system, to activate the height adjusting mechanism 4. Ina preferred embodiment, the height adjusting mechanism is connected to apneumatic system which has an air compressor 50 for maintaining apredetermined pressure in an accumulator 52. At least one pneumaticsolenoid valve 58 is connected between the accumulator and each actuator6 to control the application of the pressure supplied to the actuator 6.A manifold 56 in FIG. 10 is shown as supplying pressurized air, viasolenoid valves 58, to one or more actuators 6 under control ofelectrical signals from an operator's controller module which includes akey pad control (which may be remote) at 60. A combined electrical andpneumatic connection is shown at 62 and a manifold controller is shownat 64. The system may incorporate a pressure regulator (not shown) toadjust the amount of force (from the pressurized air) applied to raisethe soil conditioning implement.

Pressurized air is then supplied to the pneumatic cylinders 6 in a wellknown manner to the mounting assembly, which, in turn, will raise thesoil conditioning implement if the user has determined the soil in thatlocation is too wet for use, or lower the soil conditioning implement ifthe soil is suitable to use the soil conditioning implement. It will beappreciated that the cylinders 6 may be single or double acting withsingle acting cylinders used to raise the soil conditioning implementson the power stroke and allow the basket to float under its own weightwhen the pressure is released. Double acting cylinders can be used tofix the implement in a lowered position.

As also shown in FIG. 10, each of the plurality of rolling basket soilconditioning assemblies may be placed in front of each of a plurality ofseed distribution units of a planter as at 46 to ready the soil toreceive the seeds. Each of the mounting assemblies for the soilconditioners may be controlled individually or simultaneously withothers. Also, groups of mounting assemblies may be controlled. If themounting assemblies are controlled individually, the manifold 56 (eitherpneumatic or hydraulic), may supply pressurized air through the use ofsolenoid valves 58. The operator is able to control the heightadjustment and so the application of one soil conditioning implement, aspecific group of soil conditioning implements, or all of the soilconditioning implements using the control pad 60 in the cab of thetractor. As indicated, the control pad 60 may be any kind known in theart for sending control signals to solenoid or other pneumatic orhydraulic valves.

The system allows for maximum efficiency of the soil conditioningimplements, for if one row or a few of the rows in a field are too wet,but the remaining rows are dry, the user may selectively apply the soilconditioning rolling basket implements to suitable rows. The user,therefore, is able to maximize the effect of using rolling basket soilconditioning devices in a field.

FIG. 7A depicts a rolling basket device 10 in accordance with theinvention fixed to the main structural member 38 of a plantingimplement, a unit of which is shown at 35 in which the attachment plate12 is attached to the member 38 by an additional framework 70. A similararrangement is shown in FIG. 7B in which the actuator is a double actingair bag system as at 72.

FIGS. 9A-9E depict alternative actuator devices used in combination withthe rolling baskets. They include a pair of torsion springs as at 80 inFIG. 9A which are used to provide an amount of downward force on therolling basket 10. Similarly, FIG. 9B utilizes a compression spring 82connected between mounting plate 12 and cross member 24. A spring andshock absorber arrangement 84 is shown in FIG. 9C and a single actingair bag or air shock absorber is shown in FIG. 9D.

It should be noted that rolling baskets having mounting arrangementswith devices providing downward force only are normally raised manuallywhen they need to be out of contact with the soil. They are held in araised position using a manually-operated latch system such as is at 88shown in FIG. 9F.
